For solar tracking panels, H1Z2Z2-K cables have been designed with a rubber cross-linked insulation and outer sheath that makes the cable extremely flexible, as the panels will be moving along with the sun. These cables also meet the most stringent global standards for low-smoke halogen-free, fire-retardant, and low-corrosive gas emissions, are AD8, direct burial and TÜV certified according to EN 50618 and IEC 62930 Standards. They can also be rodent and termite proof cables (on request).
Application: H1Z2Z2-K is intended for use in photovol- taic power supply systems indoors and out- doors, in industrial and agriculture fields. Suitable for application in equipment with protective insulation (Class II), in explosion hazard areas and may be installed as fixed or freely suspended or free movable.
